An estimated 10,000 fans left their seats, leaving visible empty patches as Sunderland scored twice to earn a point on Merseyside.

Evans has praised the walk-out, and urged Liverpool to act.

Speaking to talkSPORT, he said: “Liverpool have tried to explain that it is only about a very few amount of tickets, but if it is about a very few amount of tickets then really it shouldn't be bothering them at all.

"They should do something about it.

“The fans’ protest was fantastic. They did it the right way. Vocally it was brilliant and the walkout was done in a very positive way without any hassle. I hope the club’s response is as good as the protest was.

“I’m sure Liverpool are sensible enough to make this not a big issue and to listen to the fans. It is supposed to be a game for the fans, whether you can afford tickets or you can’t afford tickets.

“It is a game for everybody. It is not just Liverpool by the way, it is a lot of clubs.

“Clubs say we have got these things we do for young kids, for the disabled and people that can't afford it or whatever, but it has got to be across the board so everybody can afford to watch the great game we have loved for years.

“Money can ruin everything. It is the root of all evil, as they say. I understand, of course, that there has got to be revenue, there has got to be stuff going in with players getting paid ridiculous amounts of money.

"But at the end of the day you can’t keep putting that load on to the fans.”
